Here it is again ... I use .25g/in^2 epoxy to the supplied LNC2 material. And even at that the layup is still wet. I guess some folks are more tollerant of waste than I. Admittedly I keep the waste cloth to a minimum and make epoxy quantities based on exacly what's needed. Some use the excess epoxy for other things .. good idea surely .. I can never plan for use of that extra in the bottom of the cup. I either forget to prep the area or have another crisis to attend to. Thought eveyone might like to know what a miser uses on layups tho. Even in my miserly condition, I still have used a bunch of that sticky stuff. Everyone has a "method" for applying resin to glass. To avoid bubbles and waste, I tape the plastic down and populate it with resin in the boundries of my layup. Spread it with a squeegee just thick enough that the glass will absorb it all. Lay on your first glass layer. When the glass is wet (has absorbed the resin), smear more epoxy on the top if needed and add any additional layers of cloth one at a time with more smear of epoxy. There are no bubbles using this method if you haven't "whipped" the resin/hardner during mixing! Then lay another plastic sheet on top of the layup and roll roll roll. Then I use that neat cloth cutter to finalize the shape of the part. Carry the masterpiece part to the job with the top layer of plastic. If you trap bubbles between the wet layup and the job site (use a light as below), take a paper towel wet (damp) with acetone and push those bubbles out from between the layup and jobsite, very easily, without muss. If I still have bubbles or something I need to work, use a brush with out removing the brush's plastic cover to work the problem. Remove the final layer of plastic from the part. Cover with peel ply, if desired, till cured. Wonderful layups. Just another method ... jim
